Product details
Overview
PESD5V0X2UT from Nexperia is a dual-channel unidirectional ESD protection diode in SOT23 package, designed to safeguard two high-speed data lines against ±22 kV IEC 61000-4-2 and ISO 10605 transients. It delivers 5 V reverse stand-off voltage, 0.76 pF typical capacitance, and 2.4 V clamping voltage at 8 A TLP, enabling robust protection for USB2.0 and HDMI interfaces without signal integrity degradation.
For engineers reviewing the PESD5V0X2UT datasheet, PESD5V0X2UT pinout, PESD5V0X2UT application, or PESD5V0X2UT equivalent, key selection criteria include ultra-low capacitance for <1 Gbps serial links, common-anode dual-diode topology for bidirectional line protection, and 175 °C junction temperature rating for automotive under-hood and industrial edge deployments.
Technical Context
This device implements a snap-back clamping structure with negative dynamic resistance, reducing clamping voltage during ESD events while maintaining low leakage (1 nA typ at 5 V). Its dual-cathode/common-anode configuration enables independent protection of two signal lines referenced to a shared ground return path.
Designed for transient suppression per IEC 61000-4-2 (±22 kV contact), IEC 61000-4-5 (10 A 8/20 µs), and ISO 10605 (22 kV, 150 pF/330 Ω), it operates within –55 °C to +175 °C ambient range and exhibits matched capacitance (<0.5% ΔCd/Cd) between channels for differential pair symmetry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 5 V - Ensures no conduction during normal 3.3 V or 5 V data line operation, preventing signal loading. |
| Clamping Voltage | 2.4 V at 8 A TLP - Limits voltage seen by downstream ICs below logic-level damage thresholds during ESD strike. |
| Diode Capacitance | 0.76 pF - Enables use on USB2.0 (480 Mbps) and HDMI 1.4 (up to 3.4 Gbps) without measurable eye diagram degradation. |
| ESD Rating | ±22 kV IEC 61000-4-2 - Meets highest system-level ESD immunity requirement for consumer and industrial end equipment. |
| Peak Pulse Current | 10 A (8/20 µs) - Withstands surge events per IEC 61000-4-5, including lightning-induced coupling on cable interfaces. |
| Junction Temperature | 175 °C - Supports placement near heat sources in automotive infotainment and industrial gateways without derating. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body height. RoHS-compliant, halogen-free, and qualified per JEDEC J-STD-020 moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Connects to first protected data line (e.g., USB D+); conducts during positive ESD transients on that line. |
| 2 | Cathode (Diode 2) | Connects to second protected data line (e.g., USB D–); provides independent clamping for differential pair. |
| 3 | Common Anode | Connected to system ground; serves as shared return path for both ESD current paths, minimizing loop area. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance matching | ΔCd/Cd ≤ 0.5% - Preserves impedance balance in differential signaling (e.g., USB, LVDS), reducing common-mode noise. |
| Snap-back clamping architecture | Dynamic resistance <0.12 Ω at 10 A - Achieves rapid voltage collapse post-breakdown, limiting energy dissipation in protected ICs. |
| High-temperature operation | Tj = 175 °C - Eliminates thermal derating in compact enclosures and under-hood automotive modules. |
| Bi-directional ESD protection per line | ±22 kV IEC 61000-4-2 - Single device protects both polarities of each data line without external biasing components. |
Applications
| USB2.0 Interface Protection | HDMI 1.4 Data Lane Protection |
|---|---|
Use Scenario: Protecting USB D+/D− lines in portable docking stations exposed to frequent hot-plug and human-body ESD events. IC Role / Device Role / Timing Role: Unidirectional ESD clamp placed directly at connector, before USB transceiver IC, with minimal trace length. Use Value: 0.76 pF capacitance avoids signal rise-time degradation at 480 Mbps; 2.4 V clamping prevents PHY latch-up during ±15 kV contact discharge. |
Use Scenario: Shielding TMDS clock and data channels in set-top box HDMI receivers operating in noisy home entertainment environments. IC Role / Device Role / Timing Role: Dual-channel protector mounted adjacent to HDMI receptacle, sharing ground plane with shielded cable return. Use Value: Matched capacitance ensures <0.1 dB insertion loss imbalance across differential pairs; 175 °C rating supports sealed metal chassis designs. |
| eSATA Gen II Port Protection | LVDS Display Interface Protection |
Use Scenario: Safeguarding eSATA TX/RX lanes in industrial RAID controllers where cable hot-swap induces repetitive transients. IC Role / Device Role / Timing Role: Common-anode dual diode placed at board edge, with dedicated low-inductance ground via to internal ground plane. Use Value: 10 A 8/20 µs surge rating handles coupled surges from long cables; 5 V VRWM aligns with eSATA 2.5 V signaling margin. |
Use Scenario: Securing 10-bit LVDS video bus between mainboard and display panel in medical imaging displays requiring zero pixel corruption. IC Role / Device Role / Timing Role: Channel-specific ESD clamp on each LVDS pair, routed with controlled 100 Ω differential impedance. Use Value: Sub-1 pF capacitance preserves >600 MHz bandwidth; ±22 kV rating exceeds EN 61000-6-2 immunity requirements for Class A equipment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4201MR6T1G | Higher capacitance (1.2 pF), lower ESD rating (±15 kV IEC), same SOT23-3 package | Limited to USB1.1 or slower interfaces; unsuitable for HDMI or eSATA Gen II | Select when cost sensitivity outweighs high-speed performance and system-level ESD compliance is relaxed. |
| Vishay VEML6030X01 | Photodiode sensor IC - not an ESD protector; incompatible function and pinout | Not applicable - functional mismatch | Exclude from ESD protection evaluation; this is an ambient light sensor, not a protection device. |
Compared with NUP4201MR6T1G, PESD5V0X2UT offers 36% lower capacitance and +47% higher ESD rating, making it suitable for next-generation high-speed interfaces; VEML6030X01 is functionally unrelated and must not be substituted.

FAQ
What is the maximum recommended PCB trace length between PESD5V0X2UT and the protected connector?
Trace length should be ≤3 mm from each cathode pin to its respective data line and ≤2 mm from the common anode pin to the nearest low-inductance ground via. Longer traces increase inductance, degrading clamping response during fast ESD transients (e.g., 1 ns rise time per IEC 61000-4-2), potentially allowing voltage overshoot beyond 2.4 V.
Can PESD5V0X2UT protect bidirectional data lines like I²C or SPI?
No - PESD5V0X2UT is unidirectional and only clamps positive transients on cathode-connected lines. For bidirectional buses such as I²C, a bidirectional ESD protector (e.g., PESD2CAN) or dual unidirectional array with separate anodes is required to handle both polarity transients without forward-biasing during normal operation.
Does PESD5V0X2UT require external biasing or series resistors?
No external biasing is needed - it operates passively. Series resistors are not recommended, as they degrade high-frequency transient response and increase clamped voltage (V = I × R + VCL). Layout best practice is direct connection to protected line and low-inductance ground, with no added impedance in the ESD current path.
How does the 0.76 pF capacitance impact USB2.0 eye diagram compliance?
At 480 Mbps, 0.76 pF adds <0.5% jitter to the rising/falling edges and causes <0.1 dB insertion loss at the 240 MHz fundamental frequency - well within USB-IF eye mask tolerances. Measurement data confirms full compliance with USB2.0 electrical specifications when placed within 5 mm of the connector with proper grounding.
